Effective population size estimates of B. parvus populations. (n, number of individuals sampled; N_c, adult census estimates; N_e (dir), direct estimates based on sex ratio; N_e (temporal), temporal-based estimates; N_e (IAM) and N_e (SMM) effective population size calculated under the assumptions of an infinite allele model (IAM) and stepwise mutation model (SMM), using mutation rates of 10⁻³; N_e/N_c, effective population size to census size ratio.)
